A Julia ecosystem for tensor networks and quantum many-body physics.
QuantumKitHub develops and maintains a suite of interoperable Julia packages for large-scale tensor network computations. The ecosystem spans from low-level tensor contractions and symmetry-aware data structures to high-level algorithms for simulating quantum many-body systems.
